CARRIER FOR TUBULAR DESPATCH SYSTEMS.

SPECIFICATION 'forming' part 0f Letters Patent N O. 669,890, dated. March 12, 1901.

Application filed August 10, 1900. Serial No. 26,494. (No model.)

To all whom, it may con/cern,.- L

Be it known that LWAsHING'iOW A. H. B0- GARDUS, a citizen of the United States, residing at The Montana, One Hundred and Twenty-fourth street and Mount Morris avenue, in the city of New York, county of New York, and State of New York, have invented a new and useful Improvement in Oarrierslior Tubular Despatch Systems, of which the following is a specification.

lVIy invention relates to improvements in the general class of pneumatic-despatch apparatus, and more particularly to an improved carrier for pneumatic-tube systems, its objects being to provide a simpler, more efcient, and stronger carrier than has heretofore been in use, and especially to provide improved means of securely attaching and locking the cap, means to prevent the insertion of the car rier into the tube before it is securely locked, means to prevent the detachment of thecap while the carrier is in the tube, and the elimination, as far as possible, of bolts and rivets in the construction of such a carrier. I attain these objects in the manner hereinafter set forth, reference being had to the accompanying drawings, in Which- Figure 1 is an elevational view of an end portion of my carrier; Fig. 2, a longitudinal section thereof; Fig. 3, an elevational viewof a modiiication; Fig. 4, a longitudinal section of Fig. 3; Fig. 5, an end view of carrier, showing cap removed; and Fig. 6, a detail plan of split spring-ring.

Like reference characters designate similar parts throughout the several views.

Referring to the drawings, 1 represents the body of the carrier; 2, a packing-ring thereon; 3, the cap, and 4 a buder in said cap.

mit n The body 1 of the carrier is preferablystamped or otherwise formed from steel or other suitable material in the form of a hollow cylinder closed at one end. Two or-lnore packing-rings 2, consisting of a metallic ring or felly 5, preferably provided with one or more internal annular recesses 6 and covered with a layer or layers 7 of any suitable packing material, such as vulcanized rubber and fiber, are placed upon the Ibody 1 of the carrier at suitable intervals. ,f'An expanding roll is then inserted in the bbdy 1 and the walls thereof rolled into the recess 6 of the rings 5,

and the walls of the body 1 and rings 2 sweated together by the insertion between Vthem of a metallic cement and the applicathis recess 1() is placed an elastic seal 12, prefg erably taking the form'of an ordinary hollow inflated pneumatic tire calculated to make the carrier water-tight. When it is not desired to provide a water-tight carrier, a split spring-ring 13 (shown in detail in Fig. 6 and also in Fig. 3) may be used, attached in any suitable manner to the top portion 9 of the cap 3. The top edge of the body l of the carrier is preferably turned to form a wired bead 14, which is designed to form a seat for the seal 12 of the cap 3. The wall 11 of the cap is extended in two or more places to form legs 15, having hooked ends 1G and adapted to pass through the recesses 8 of the upper ring 5 and their hooked ends 16 designed to engage the lower edge of the ring 5 when the cap 3 is rotated in this position on the body 1. A spring 17, lying substantially parallel to ring 5 and having one end 18 seated in a recess 19 in the ring 5, is secured therein by the ring-securing means and a set-screw 20. The free end of spring 17 is provided with an enlarged port-ion 21, beveled on its upper inner edge to ride up on the leg 15 and its end squared to fall behind a low leg 15 when the cap has been rotated until hooked end 16 engages the under side of ring 5, thereby positively securing the carrier from coming open. The enlarged portion 21 of the spring 17 is of a thickness sufficient to just clear inside of the packing-ring when the carrier is locked and the spring has fallen behind leg 15, but will project beyond the ring 5 and prevent the carrier from being inserted in -the tube when the spring is not so far behind the leg, but bears upon the outer surface of the leg, the carrier not being securely locked. A buf- IOO fer 4, consisting of several layers of leather cemented or strapped together or of other material, is sprung into place between the flanges formed by the recess 10, being stamped or rolled up and cemented or otherwise fastened to the top portion 9 of the cap 3. It Will be seen that this construction of the cap produces a tighter joint at the seal, as more pressure is brought to bear upon the top portion 9 of the cap.

In the modification shown in Fig. 3 the spring 17 is fastened above the ring 5, and straps 23, carrying lugs 24 and retain-angles 25, secured in recess 26 of ring 5, are substituted for the recesses 8 in Fig. 1, the legs 15 being shortened, their hooked ends 16 engaging legs 24, inside of ring 5, directly upon the cap being rotated.

To apply the cap to a carrier, it is placed upon the' body portion 1 and the legs inserted in recesses 8, then pressed down, the beaded edge 14 of the body engaging the seal 12 until the hooked ends 16 clear the ring 5, thereby rendering the carrierWater-tight, and the spring 17, by reason of its beveled inner edge, has ridden up upon th`e leg 15. Then the cap is rotated in the direction of the hook 16 until said hooks have passed under the solid portion of the ring and the springs 17 have fallen behind legs 15, locking the cap in place. To open the carrier, a pointed instrument of any suitable shape is applied under spring 17 and the said spring raised, allowing the hooked portion 16 to be rotated from .under the solid portion of the ring, and the cap removed.

It is obvious that various changes may be made in the construction and detail of this device Without departing from the spirit of my invention.

Having now described my invention, what I claim, and desire to secure by Letters Patent., is-

1. In a carrier for pneumatic transit-tube systems, a body portion, a lid therefor, a plurality of arms upon said lid extending longitudinally of said carrier, hooked ends for said arms, projections upon said body portion for engaging said hooked ends and a latch on said body portion for locking said hooked arms in engagement with said projections, substantially as described.
